Description

Handle fast-assembling ball valve

Technical Field

The utility model relates to a ball valve field especially relates to a handle fast-assembling ball valve.

Background

The ball valve is a valve which is opened and closed by rotating the ball body around the central line of the valve body, the ball valve is mainly used for cutting off, distributing and changing the flowing direction of a medium in a pipeline, the existing ball valve is complex in structure and inconvenient to disassemble and assemble, the sealing effect after recombination is poor, the stability is poor, the force required by control in the using process of the ball valve is large, related parts are easily damaged, the rotating precision is not high in the using process, and the slippage is easily caused to offset the flow size. To this kind of condition, the utility model provides a fast-assembling sealed ball valve through the improvement to current fast-assembling ball valve, solves the condition that poor stability, rotation precision are not high, great and the life that causes hard reduces through the simple structure, realizes the simple quick installation of ball valve and dismantles, and stability is good, convenient and practical improves the life of ball valve.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the problems, a handle quick-assembly ball valve is provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a handle fast-assembling ball valve, which comprises a valve body, the spheroid, the handle, its characterized in that valve body is fastened through the stud of fastening usefulness by both sides valve gap and middle flange piece, the spheroid is located middle flange piece and cooperates with the disk seat, the spheroid top is equipped with recess and valve gap cooperation, the valve rod is close to spheroid one side and is equipped with thrust washer embedding, the valve rod is close to handle one side and is equipped with gland packing and seal cover, the valve rod top is equipped with double-deck nut, locking valve gap and valve rod, be equipped with the packing ring between nut and the locking valve gap, be equipped with the dish type packing ring between nut and the valve rod, the handle is located locking valve gap top.

Preferably, the top of the ball body is provided with a groove which is matched with the valve cover in an embedded mode, and the valve cover is matched with the valve rod in a buckled mode.

Preferably, the valve covers on the two sides and the middle flange sheet are provided with corresponding through holes at the corresponding positions of the stud bolts, and the stud bolts are fastened at the through holes.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the handle is realized through the locking part which is convenient to disassemble and assemble, and the traditional nut is better replaced for fixing, so that the disassembling and assembling process of the handle is easier and more convenient, and the effect of conveniently maintaining and replacing the handle is further achieved.
